Patented Nov. 17, 1931 srrss PATENTO HERBERT C. BUNTING, OF SEATTLE,WASHINGTON, ASSIGNOR TO NATIOTTAL VENDING SERVICE, INC., OF CHICAGO,ILLINOIS, A. CORPORATION OF ILLINOIS SINGLE PACKAGE VENDING MIACHINEApplication filed December 10, 1921, Serial No. 521,328." Renewed August4, 1930.

Myinvention relates to vending machines and particularly to such as areadapted to hold and deliver a single package, also to such as retain thecoin in full view until the machine is reset, and only then to releasethe coin.

The primary object of my invention is to provide a vending machine whichwill accomplish these purposes, namely, to deliver its single packageand to retain the coin in its op crating mechanism and only to releasethe coin when the machine has been reset or reloaded.

Associated with the generalobject above, it is my object to produce acompact and neat vending machine.

A'further object is to provide means in a vending machine which willlock either the coin-controller mechanism or the package handlingmechanism, or both, in actuated position, that is, in the positiontheparts assume after a package has been delivered.

A further object is to provide a vending machine in which'the parts areso locked in actuated position and which requires specialmanipulation,or in some cases a special key or releasing tool, to resetparts in thenormal position. 7 I

Otherobjects will beascertained from a study of the followingspecification and. claims and the drawings which forma part hereof. w

invention comprises those novel parts and combinations thereof which areshown in the accompanying drawings, described in the specification, andparticularly pointed out in the claims terminating-the same. 7

In the accompanying drawings I have shown my invention in the form whichis now preferred by me.

My vendingmachine is particularlyadapted for use in public places whereit must necessarily be small and inconspicuous, by reason of lack ofspace, of harmony with its surroundings, or for other reasons. I havetherefore shown my device as vending only a single'package, as ofchewing gum. v

\Vithin a casing 9 is slidably mounted a carrier 8 provided with fingers81 at its outer end, which are adapted'to engage the'outer end of thepackage P to retain it within the machine. The carrier 8 may alsosupport an ejector plate 82 atits inner end, backed'by a spring 83, forlimited movement relative to thecarrier, but this must not be confusedwith the primary ejector which will be later described. The plate 82 andspring 83 are merely supplemental ejeetorsto give a final push to thepackage itself. V r i The carrier 8 is guided in confined guides 94 ofless width than the casing 9, the distance between them being slightlygreater than, the width of the package P. At their ends the guides 94are cut away, and opposite si'desofthe. delivery opening 91 from thecasing 9-are provided with inturned hooks 95 which are adapted toreceive the hooked ends 81 of the carrier. The endsof the carrier arearranged to spring outward when they are released from the confiningguides 94, as is shown by dot-and-dash lines in Figure 2.Theicarriervhas a certain amount of spring, as is shown by comparing itsstressed. and unstressed forms, in Figures 2 and 9, respectively. Acatch 85 of spring material is secured to move with the carrier 8 andmay be provided with a lateral oiiset 86 for a purpose to be laterdescribed. This catch 85 engages with a fixed catch 98 upon thecasing 9and retains the carrier 8 therein until the catch 85 is released. Thecasing 9 is pref erably provided with suitable windows 96 and 97adjacent the positions assumed by the package and by the coin,respectively.

A coin slide 10, guided'suitably, as in car rier 93 removably secured inthe casing 9, is

provided with a suitable opening 11 for the reception of a coin, thecasing 9; having an opening 90 registrable with the opening 11 whenparts. are in their normal position- The slidev 10. may also. beprovided with a suitable V handle 12. The coin slide isshown. as uidedthe coin slide carrier 98by means o a rib 93 slidable-in a slot 92. Adouble ratchet bar 1 is suitably secured to the coin slide 10 to movetherewith, asby means of pins or rivets 13. passing through the slide10, rib. 93" and bar 1:, and these members are to all intents and"purposes integral one with the. other, though theratchet bar 1 is.spaced from the coin slide 10=by a partition of the carrier 93; l Aspring let-anchored at one end to1thecasing and secured at its other endto the coin slide onto. apin 13v which. is projectedthe'refrom outsideof the carrier 93, serves to. retaingthe coin; slide in its normalposition as shown in- Figure' 5'.

. On. one side of the; ratchet. bar lare teeth 15-, which, are adaptedto be engaged by a dog 2;which is; pivoted at 2Q in the casing '9" andwhich is held in the path of the teeth 15 by the actuating orxejectingdirection.

Y carrier release 16' is supported at the inner end of the bar .1, bemgthat end which is adjacent the carrier 8; Preferably it projectslaterallyand is intended to; engagev the laterally projecting-member 86which forms part: of the catch 85.. These two members have theirsupports-out: of alinement with any portionof the other memberso thatthey may: not. be engaged toblock-the operation of thefmechanism atanytime. The carrier-release 16 ispositioned tooperate only aftertheteeth15 havepassed' the dog 2; and; upon suitable: engagement oft-hemembers. 16 and 86the catch. '85-.isreleasedl' from the fixed stop98'i3i1'1d'6j68l3l0I1-01l"l3l1fi carrier8 with its package P ispermitted. The forward edge 18 of the support for release 16, or anyother member movable with the coin slide 10 and ratchet bar 1. contactswith a boss 88, or other portion of the package carrier 8, to give it aslight initial push and to start it in the ejecting direction.

Means may be provided for locking the package carrier 8 in ejectedposition, to be releasable only as. a new package is placed in position.within the machine. A spring catch 7 is secured to the casing 9 inposition to engage the carrier 8 in its ejected position;

preferably at its inner or upper end. A bend 71 forming part of thecatch 7, lies in the path of the plate 82. Ordinarily, whenthe machineis loaded, the catch 7 lies alongside of the carrier 8, but engages thecarrier when this moves outwardly. As a fresh package is pushed into themachine, it engages and moves inwardly the plate 82, the latter in turnengaging the bend 71 to force the catch 7 outof engagement with thecarrier 8, whereupon the carrier moves inwardly to its normal or loadedposition, where it is 'held by the catch 85.

Means are provided for locking the coin slide in the position it assumesupon ejection of the package P, with the coin in full view through thewindow 97 I have shown the ratchet bar 1 as provided with teeth 17whichface oppositely to the teeth 15. and which maybe upon the oppositeside of the bar 1. A second dog 4' is pivoted at in the casing 9 and isnormally held in engage ment with: the teeth 17 by means of a spring 41.,A pin- 42 stands above the surface of the dog 4 to.- beengaged by areleasing trip.

1 Juli,

The releasing; trip 5 is. carried upon a lever .50 pivoted; at 51 uponthe resetting} slide 3,

in: position to engage the pin 42- as it passes, the slide being guidedupon pins 30 supported from the casing 93 and passing through slots 32of the slide The trip 5 is shown asuponf the opposite side of theresetter 3 from the lever 50, the pin. 52- connectingit to the lever 50passing through a slot 32- and havinglateral movement only therein. Thetrip his-inclined upon: both faces relative to its direction ofmovement, and; as: it passes outwardly of' the pin 42' moving towardsthe package carrier: 8, into. its normal position, thealever 50 is movedto one side and. the positionof the pin 42 and dog 4is not disturbed;

Upon being moved in theopposite direction,

however, by engagement of a special: reloading tool: T', shown. bybroken lines in Figure 2, with an upturned toe 33 of the resettingslidei3 the opposite face of the tripe engagesthe pin=42, and the pin 52being held against inwardmovement by the edge of the slot 32, the pin 42and the dog 4 are forced outwardly, in this manner to release the dogfrom the teeth 17. As this occurs-the action off the spring 14 which hasbeen extended, 3

, slide is it may be ing tool able recesses or openings returns the'barland the coin slide 10 to their normal position. vIt will be seen thatthe spring 8l'is extended between a fixed post '30 and apost 53 carriedupon the lever 50, and thus-serves both to maintain the lever 50 andtrip 5 in proper position, and to maintain the slide 3 in operativeposition, except the coin is visible through the window 97 to preventthe use of slugs. However, if a proper coin is inserted in the recess11, this will contact with the pin 22 to move the dog 2 out of the'pathof the teeth 15; Immediately thereafter the dog its teeth 17 to preventreturn of the coin slide to normal position. However, as the pushedfarther in the actuating direction, its handle 12 may enter a recess 99in the casing which is adapted to receive it, and eventually the release16 engages the member 86 to release the catches and 98. At this instant,as shown in Figure 4:, the ejector edge 18 of the ratchet bar contactswith the boss 88 of the package carrier, initiating the ejection of thecarrier 8 with its package P.

Once free of the confining guides 94, the ends 81 of the carrier springoutwardly and force the entire carrier to move towards the deliveryopening 91. The'ends 81 are finally received within the hooks 95. Theaction of the supplemental ejector plate 82 then assists in the furtherprojection of the package P beyond the limit of the delivery opening 91to a point where it can be grasped, although the inwardly bowed sides ofthe carrier keep it from falling out. By this time the coin slide hasadvanced the coin until it is opposite the circular window 97 whereplainly seen, and as the machine will be used in public places, thiswindow will show what has been inserted and this fact will act as agreat deterrent to the use of slugs. teeth 17 has locked the slideagainst return movement.

To remove the coin it is necessary to withdraw the slide 10, and thiscan best be accomplished with the use of the key or reload- T, althoughthe device may beso arranged that the mere insertion of the package willrelease the coin slide. This reloading tool may be made in variousshapes, and the faces of the ejector plate 82 and the inner end. of thecarrier 8 may be formed with suit- 88 to receive the key.

the recess 11, the .dog 2 will 1 is engaged Wlllh combination a coinslide,

Engagement of the dog 4 with the lhis is inserted from the deliveryopening and is passed through the holes in the plate 82 and the end of,the carrier 8, which are best shown in Figure 8 as notches 89, until itcan engage with the foot 33 of the resetten: gether with theinsertion ofthe key a new package P would ordinarily be pushed into position in thecarrier 8 and this wouldbe pushed into the casing 9 with the key untilthe catches 85 and 98 were again in engagement. At the same time theresetting slide 3 would be pushed back in the same direction, and asthetrip 5 passes the pin 42 the dog 4; is released and, asdescribedabove, the action ofthe spring .14 returns the rack bar 1 i and the coinslide 10 to its normal position. The coin can then be, removed throughthe opening by which it was inserted, and the mzlichine is loaded andready for another ea c.

r In case of any defect in the coin-controlled mechanism, or if it isever, desired to remove the same for any reason,- the carrierorinnercasing 98 may be removed bodily from the outer casing, and as all ofthecoin-controlled mechanism is secured thereto, it may an be removed atonce,.and as a unit;
